LOG-IDYJEING MACHINE.

Specilcation of Letters Patent.

Patented Sept. 4, 191'?.

Application led February 2, 1917. Serial No. 146,239.

To all whom t may concern:

Be it known that we, HERMANN FINGERLE and KARL KROUPA, subjects of the Emperor of Germany andthe Emperor of Austria,

respectively, and residing at New York, in

thecounty of New York and State of New York, have invented Vcertain new and. useful Improvements in Log-Dyeing Machines, of

` which the following is a specification.

This invention relates to logl dyeing machines and has for its object to provide simple and eiicient means for forcing liquid (fiyes through entire logs, so as to dye lthe ers thoroughly, at the same time driving out thesap from the pores of the wood. `A

- further `object is to provide such means yin section and .wherein a plurality of logs may be dyed simultaneously, even if the logs are of different diameters. A still further object is to provide means whereby logs of irregular shape may be dyed, by the above described process, in their entire thickness, without wasteof the irregular protrusions.`

With the foregoing and. other objects in view, the invention consists in the particular construction, combination and arrangement of parts hereinafterdescribed and shown in the accompanying drawing, in which:

Figure 1 is a partly sectional, partly elevational view of the device, showing two logs one in elevation inserted therein;

Fig. 2 is a plan view of the same, showing lone half of the circle, the other half being identical therewith, ,and partly broken away to show hidden parts;

Fig. 3 is a fragmentary plan view of a -v portion of the device, on'an enlarged scale.

Like reference characters designate like parts in the different views.

Referring more particularly to the drawing, 4 is a brick work base on which are mounted pedestals 5 supporting nthe base vplate 6 of the machine, which is preferably edge"of the ring, in a radial direction and.A

communicating by passages such as 12 with tlie surface of the ring intermediate the two eXtreme ends of the passages 11 and in that portion of the surfacewof the plate designed as'a seat for a log end. Pipes 13, secured into ports 145 .provided in the bottom of the 'base plate,correspondingly to each` passage 11, lead to and support a centrally located tank or reservoir 14`and are provided with valves 15 enabling each of the pipes 18 to be opened individually and independently fromthe others to 'communication with the tank 14 or to be shutoff therefrom.

The logs 16, 17 and `18 are each placed on the baseplate 6, in positions corresponding to the passages 11, packing rings 19 being first inserted between the bottom of the logs and the top of the base plate. rlhese rings 19 are preferably of rubber or similar resilient material and conform in shape and size to the circumference of the respective logs.

Similar packing rings 20 are inserted between the top Vof the logs -and the bottom of the top plate 7, whereupon the latter is forced downward, by turning. the nuts9 and 10, and thus air tight joints are formed between the two endsvof 'the logsand the respectlve plates 6 and 7, leaving chambers 21 85 into which the passages 11 andv 12 abutand chambers 22 on top, fror'nv which` passages lsuch as 23, formed in the top plate 7, lead to the inner edges of the'latter, under which is fastened a funnel shaped liquid collector 24.

The dye is forced into the reservoir'14, under pressure, through a pipe 25, then proceeds through the pipes 13, ports 14', passages 11 and 12, into the chambers 21 and from there through the logs, driving the sap out before it and the latter, with the surplus dye, vemerges on the top of the logs into the chambers` 22 and from there, through the passages 23, into the collector 24, wherefrom itvmay be conveniently conducted to any desired place bymeans of a hose-k attachable to the outlet 26 of the collector.

When a log of smaller diameter than the distance between the extreme ends of the passages 11 is desired to be dyed, as for instance shown by the log 17, as many of the ports of the passagesll andr 12 as may be l left outside of the packin rings 19 will be lugged air tight, as at 2 As shown in MIP@ ig. 2, where the top plate is partly broken easily be shaped to conform' to the irregular` contours of the logs and thus permit to dye the logs all over, without losing the protruding portions.

To the outlet 26 of the liquid collector 24 is fastened a ring 27 having, integrally formed therewith, radial 'arms 28, with extensions 29, adjustably secured thereto. To

the outer ends of the extensions 29 are'pivotally secured the shackles 30,-. provided with hooks 31 at their respective outer ends. Chains 32 are hitched on the hooks 31 and encircle the logs so as to hold them securely in their respective positions between the top and base plates. Claims 1. A log dyeing machine comprising, in

' combination, a base and a top plate adapted to hold therebetween a plurality of logs of various diameters, standmg vertically, packing rings to form air tight joints between the ends of the logs and the `respective plates, said packing rings being adjustably conformable to the respective circumferences of the ends of the logs, means to tightenthe base and top plates togetherto hold the rings compression, assages formed in the base plate for the a mission of dyes and in the top plate for the outlet of the sap each o said passages for the admission of` liquid, each of said means of communication being adapted to be opened or closed individually, irrespective of the others, sai'd' outlet passages all abutting into a common collector ofv liquidyand means connected to said li uid collector for 'supporting logs clamped between said plates securelyr 1n position.

3. A lo impregnating machine having upper @an lower members provided with log end seats for respective engagement with the upper and lower ends of a vertically' disposed interposed log, one of'said members being movable toward and from theV planeof the other and both being provided with liquid conveying passages having outlets at said seats, means for adjusting the movable member towardthe other memberto secure iuid tight joints betweensaid seats and the extremities of an interposed log, and means for introducing fiuid under pressure to the passages in the lower member to upwardl traverse the ain of the log.

4. A" o krimpregnatlng machine having upper and ower members provided with log end seats for respective engagement withv the upper and lower ends of a vertically disposed interposed log, one of said members being movable toward and'from the plane of the other and both being provided with liquid conveying passages having outlets at sald seats, means for adjustingthe movable member toward the other member, adjustable means at 'the log end seats for defining the areas of exposures of said outlets to correspond with the diameters of the proximate log ends, and means for introducing fluid under pressure to the passages in the lower member to upwardly traverse-the grain of f the log.

. 5. A log impregnating machine having upper and lower members provided with log en d seats for respective engagement with the upper and lower ends of a vertically disosedinter osed log, one of said members of the other and both being provided with liquid conveying passages having outlets at sa1d seats, means for adjusting the'movable member toward the other member, adjustable means at the log end seats conformable in Loutline tothe peripheries Loir' the proximate log ends, to define the extent and shape of the areas of exposure of Y said outlets,
